Thanks for your suggestions. Can you provide some reasons for choosing
the itg3200 and bma180 over the mpu6000? I really like the single
package and the motions processor functionality that the mpu6000
offers. (Also, I have some of the mpu6000 and mpu6050 chips floating
around waiting for a viable project to use them in)
Well, availability. If I go to the Invensense shop and try to buy a MPU6000 they
say
"The MPU-6000 is not currently available. Please contact us for availability of this item."
But that may change soon and the MPU chips may be a good choice.
The BMA180 is listed at DigiKey.
What does the ++ reference? Is that indicate approval?
Yes, because Linux drivers exist from the Openmoko activities.
If this mother would be under the BeagleBone, the daughters could be on top of it. Great flexibility. On the mother there could also be just a duplication of the expansion connectors for easy access to all signals.
An example of the I2C sensor board implementation is shown in http://chonyota.net/freerunner/FRNBv3/. This is the Navigation Board of the FreeRunner project. I have no affiliation to it. I understand that there are working Linux drivers available for the board. Another helpful starting point.
This is the type of flexible jumper that I am talking about. It could be the link from the BeagleBone to the first
daughter board with a female (of course) connector towards the top of the BeagleBone.
Ahh, the ivensense website is apparently being unfriendly. I have
some MPU-6000 and MPU-6050 that I was able to get through their
distributor. (Component Distributor inc.)
About the motherboard. Would be really nice to have
a Beagleboard compatible expansion connector on it.
Located so that the existing Beagleboard expansion boards
can be easily mounted on it.

It's 3.3V instead of 1.8V, so I expect lots of tears when plugging in beagle classic expansionboards.
Yes they can. Like add cost. I think if this is really needed, then a dedicated board should be created so as not to add cost to every board created. Just make one only as a BeagleBoard adapter. There are not that many boards out there commercially available, so I have my doubts as to its commercial viability in the long run.
